Tiivistelmä
Recovery boiler plays an essential role in the production of pulp and paper products. In recent years, pulp and paper industry has undergone significant changes and the renewal process is going on intensively. Recovery boilers of new generation with high-energy production and fewer emissions ensure universal access to affordable, reliable, and modern energy services.
The main target of the study is to review possible boilers’ technologies to produce clean
energy and to compare its power-to-emission ratio with other kinds of boilers. The thesis
is directed to prove the advantages of recovery boilers with improved energy production
(RBIEP) to generate CO2 neutral energy.
The calculations in this thesis were based on data reported by companies - owners and
manufacturers in official open sources. Three companies were selected for comparison,
which CO2 emissions data was published in different years: RBIEP, conventional recovery
boiler, and gas boiler. The implementation of the thesis consisted of the following stages:
data collecting, calculations, comparison.
Based on the results of the calculations, it was proved that recovery boilers with improved
energy production have much higher power production and lower amount of CO2 emissions.
Also, it was demonstrated that technologies used in such boilers allow decreasing the volume of other emissions into the atmosphere that makes pulp and paper industry production more environmentally friendly.
